problem with data value = maxValue

[keithh0427]

I belive there is a small "bug" in the code for displaying colors and a legend.

consider the following:

<?php

$dataArray[0][1]="IL"; $dataArray[0][2]="10";

$dataArray[1][1]="IN"; $dataArray[1][2]="0";

$dataArray[2][1]="IA"; $dataArray[2][2]="0";

$dataArray[3][1]="MI"; $dataArray[3][2]="1";

$dataArray[4][1]="WI"; $dataArray[4][2]="2";

 

// Declare $strXML to store dataXML of the map

$strXML = "<map animation='0' showShadow='0' showBevel='0' showMarkerLabels='1' fillColor='F1f1f1' borderColor='000000' baseFont='Verdana' baseFontSize='10' markerBorderColor='000000' markerBgColor='FF5904' markerRadius='6' legendPosition='bottom' useHoverColor='1' showMarkerToolTip='1'  >";

// Opening MAP element

$strXML = "<map showLabels='1' includeNameInLabels='1' borderColor='FFFFFF' fillAlpha='80' showBevel='0' legendPosition='Bottom' >";

// Setting Color ranges : 4 color ranges for population ranges

$strXML .= "<colorRange>";

$strXML .= "<color minValue='1' maxValue='5' displayValue='0 - 5' color='FFD33A' />"; // CC0001

$strXML .= "<color minValue='6' maxValue='10' displayValue='6 - 10' color='CC0001' />"; // FFD33A

$strXML .= "<color minValue='11' maxValue='15' displayValue='11 - 15' color='069F06' />"; // 069F06

$strXML .= "<color minValue='16' maxValue='20' displayValue='> 16' color='ABF456' />"; // ABF456

$strXML .= "</colorRange><data>";

// Opening data element that will store map data

// Using Data from array for each entity

for($i=0;$i<=4;$i++){

$strXML .= "<entity id='" . $dataArray[$i][1] . "' value='" . $dataArray[$i][2] . "' />";

}

// closing data element

$strXML .= "</data>";

// closing map element

$strXML .= "</map>";

// Finally Rendering the World8 Maps with renderMap() php function present in FusionMaps.php (that we have inlcuded already)

// Since we're using dataXML method, we provide a "" value for dataURL here

print renderMap("FusionMaps/FCMap_USA.swf","",$strXML,"firstMap", 750, 460,0,0);

?>

the color is not displaying if the array value is equal to the max value in the color range.  I have to increase the maxvalue by 1 to the get the desired results.  However, this will throw off the range when I do this dynamically with a database.  I cannot check the max value each time to see if a value is equal to it.

Is there a work-around?

I believe I have solved the problem.  The $dataArray MUST be in sorted order.  I discovered this accidentally, but it seems to have worked.
